Market and application of polyester spunbonded nonwoven products
Building materials include a wide range of materials. The materials involved in spunbond nonwovens mainly refer to roof waterproof materials, followed by wall insulation and sound insulation, wall base waterproof, pipe protection, underground drainage and prevent root growth from encroaching on buildings and other USES.
At present in our country, the application mainly focuses on the field of roof waterproof material.
In Europe and the United States, especially in Europe, since the end of the 1980s, the early 1990s has been widely used this superior waterproof material, its market share of more than 40%, and most of the PET spunbond matrix.
In China, the application of polyester felt matrix started late, but the amount of 20 million m2 in 2000.
But since entering new century, new waterproof material gets rapid development.
By 2002, the use of modified asphalt waterproof rolling material based on PET fiber reached 70 million m2 and continued to increase.
It is predicted that in the next five years, the modified asphalt waterproof rolling material will still develop at a fast speed, and the proportion will increase to more than 20% by 2010.
The potential market of new waterproof materials in China is very large (about 800 ~ 1 billion m2). With the continuous in-depth development of China's economic construction, PET spunbonded asphalt felt matrix has an optimistic development prospect.
The application of geotextiles abroad began as early as in the 1960s. The United States is the country with the largest consumption of geotextiles in the world. Its annual consumption of geotextiles exceeded 300 million m2 in the early 1990s and reached 700 million m2 in recent years.
Geotextiles in Europe and Japan have also developed rapidly. In recent years, the annual consumption of European geotextiles has reached about 400 million m2, among which spunbonded nonwovens account for about 60% of nonwovens.
The application of geotextiles in Japan has increased significantly since the mid-1990s.
Among Japan's nonwoven geotextiles, spunbond method has the largest amount, accounting for about 60% of the total nonwoven geotextiles, especially PET spunbond.
